Author Topic: Simutrans 101 on Linux - loading is HORRIBLY slow (Read 8277 times)

kuba_10 · « **on:** May 09, 2009, 04:30:57 PM »

I've installed Simutrans 101 with Synaptic on the Ubuntu 9.04 x64. Then I installed pak128 and now even small maps (256x256) are taking not less than 10 minutes to load, and 512x512 loads even half a hour. I haven't experienced problems like that on Windows and ver 100... I have 4 gigs of RAM, E8400 C2D processor, so it can't be hardware. Anybody has an idea on what's going on with the game?

Mmmm...seems you've a 64 bits processor. Some other Linux users have reported the same problems. The issue is that there's no 64 bits version of Simutrans, but perhaps the problem is due to the libraries, possibly SDL but I don't know if there's a 64 bits version of that library.

Looks like I must downgrade to 32-bit and wait till 64-bit gets more popular... even YT is not working properly.

Mmm... and it seems like there's no great rush to upgrade to 64 bit chips by most people out there... Like the problem of IPv6, it seems...

Kuba,

can you check whether you have any problems with the GUI in the depot window with the 64-bit version?

I wonder whether anyone could compile a 64-bit version. Is it possible to cross-compile from a 32-bit platform? I know that Simutrans is supposed to be compatible with 64-bits.

YOu can built 64 bit version, but only with no midi sound. Maybe that is the problem, SDL_mixer is reported to have severe issues with the wrong versions. And compile with DEBUG enabled, as several versions had a problem for missing DEBUG.

jamespetts · « **Reply #6 on:** May 09, 2009, 08:51:13 PM »

How would one build a 64-bit version on a 32-bit machine?

There just is no big pressure and no big incentives for most of the people. It'll be a slow migration, but it will happen eventually.

kuba_10 · « **Reply #8 on:** May 10, 2009, 04:14:01 PM »

I'm new to Linux, it's been two weeks since I migrated from XP. So I'm still not able to customize anything while compilating... Anyways, GUI in the depot looks just like on the Windows version. No problems except the one I described and no MIDI at all (which is not a big problem for me...

)

prissi · « **Reply #9 on:** May 10, 2009, 09:03:53 PM »

Then turn midi off completely by using -no_midi on the commandline. This may improve loading times dramatically.

also version 102 is very slow on linux. I have amd processor 64bit, but the linux sistem is 32bit.

prissi · « **Reply #11 on:** May 11, 2009, 08:40:33 AM »

I have and AMD system and it is not slow. Thus I think you need to say what you have done and which pakset you are using. And did you use the binary from sourceforge?

irontux · « **Reply #12 on:** May 11, 2009, 11:17:39 AM »

I have used file .bin download to sourceforge. Whit packset 128 and 64.

kuba_10 · « **Reply #13 on:** May 11, 2009, 06:18:48 PM »

I said it's from Synaptic. I'll try a Sourceforge version. Even now I've got another bug - no matter how many factories I choose, the map creator creates only 3 - 4 factories.

~~I downloaded the Windows version 'just for kicks' and it's creating maps quickly, but the game itself is impossible to play (1-2 fps during fullscreen). So I will use it only to create maps.~~
Gah, the Windows maps won't work with the Linux game...

jamespetts · « **Reply #14 on:** May 11, 2009, 06:56:50 PM »

Presumably, you're using WINE?

prissi · « **Reply #15 on:** May 12, 2009, 09:59:24 AM »

Do not use wine, better use the native versions. I have no idea how the screen copy calls work under wine. I would not be surprised to be very slow then.

kuba_10 · « **Reply #16 on:** May 12, 2009, 04:55:00 PM »

I say, it was only in purpose of creating the maps. The maps won't work though, so it was unnecessary.

wernieman · « **Reply #17 on:** May 15, 2009, 10:35:40 AM »

Normaly there is no big Problem to compile simutrans for 64bit for me, BUT .....

I don´t see a advantage over a 32BitVersion.
See the diskussion in this forum
- Bigger Pointer
-> More Memory
-> More copy (64 Bit versus 32 Bit) in SubRouttines
- Bigger Map
-> More Memory
- .....

kuba_10 · « **Reply #18 on:** May 17, 2009, 08:27:33 PM »

I switched back to Windows for a while... and no signs of improvement. And what I see, is that preparation of a 320x320 map with 100 cities, 150 factories and 125 tourist attractions takes version 100.0 half a minute, while on 102.0, no matter which platform, it takes 3 hours. Also on netbook with VIA C7 1200/1GB and WinXP. That is abnormal, please help!

prissi · « **Reply #19 on:** May 17, 2009, 09:15:26 PM »

125 factories mean 125 factory chains, i.e. something of about 600-1000 factories. This is a completely insane setting. (On simutrans 100.0 the placement code was somehow broken, after 25 retries it gave up, resulting in crashes and many incomplete chains.)

You number of factory chains better not exceeds the number of towns much. 16 is probably a reasonable upper limit.

kuba_10 · « **Reply #20 on:** May 19, 2009, 06:04:04 PM »

Prissi, even lowering factory chains to 10 hangs up game for at least a hour. Something is wrong with object placement, I think. Blank maps are loaded quick. Has any 102.0 user experienced any similar problem?

prissi · « **Reply #21 on:** May 19, 2009, 08:00:13 PM »

Not that I know. Could you make a screenshort of your new world dialoge.

kuba_10 · « **Reply #22 on:** May 22, 2009, 04:25:20 PM »

Here you are, this is from Windows 102 version.

As far as I see, sometimes it loads quick, but more often it blocks up.

Combuijs · « **Reply #23 on:** May 22, 2009, 05:50:23 PM »

That is not the new world dialog. Prissi wants to know with which settings you are starting a new map. Take a screenshot before you start a new game and post it here.

Isaac.Eiland-Hall · « **Reply #24 on:** May 23, 2009, 02:38:52 AM »

In other words, it's the screen that shows the map number, the climate/roughness/etc settings, even language...
